Remove the plastic, frame back and picture inserts from the picture frames.
Put the tabs back down to hold the glass in place.
Glue the corners of the picture frames together. Be sure to align it evenly. Hold together firmly until each frame dries (about a minute). Be generous with the glue because you want it to hold up well. Also, I glue the inside of the corners to make sure it holds.
Using a pencil, trace the outline of the lantern onto the foam board.
Cut out the outlined section of the foam board.
Trace the outline of the foam board onto the back of the contact paper with the pencil. Add an extra ½ inch to the top and side to cover the sides of the foam board.
Make two cut outs of the contact paper using the first one as a guide for the second one.
Cover the front and back of the foam board with the contact paper. Be sure to cover the sides as well.
Glue the foam board base to the bottom of the lantern.
